I know the problem is 1000000 times here, but my SG is laggy. I did everything.

SG 1.0 don't run cause of missing OpenGL. But it's Win7 problem. Than i upgraded to 1.1b4. Followed the instruction precise. And it works. All fine. But its laggy. Damn laggy.Tried to solve the problem. Took the new binary, deleted the config, but nothing helped. Still laggy.Worser than this.. my brother got exactly the same pc. But he installed.. and it works perfect.
